The corgis who appeared in The Queen took the Best In World prize as well as the honours in the Best Historical Hounds category.
Comedy Canine, for romantic comedy work, went to Year Of The Dog; Blockbuster Bowser for an action film went to Shooter; while Cupcake Cinema for short film went to Dog Flap.
The Festival Fido prize for a canine performance at the London Film Festival went to the huskies in Asif Kapadia's Far North, with a special mention to Frozen.
The awards are the brainchild of Toby Rose, who produces the Palm Dog contest in Cannes.
Some of the winning dogs, including the corgis pictured above, were on hand at London's National Film Theatre to accept the honours. The corgis are owned by Liz Smith of Ipswich, and the pets were discovered at an obedience competition by a film and TV scout.
Dame Helen Mirren, who starred in The Queen, was in the US and unable to attend the Fidos but she sent along congratulations: 'I know one should avoid acting with animals and children but these little chaps were a pleasure to work with and deserve all the plaudits for their fine performances.'
Presenters at the Fidos were director Hugh Hudson, actress Maryam D'Abo, Carol Thatcher, Christopher Biggins and designer Lulu Guinness.
Rose said: 'The inaugural Fidos are a first in more ways than one: the first time that an interanaional A list film festival had included invited dogs onto the official programme. And the first time they have been allowed into the NFT building.'
The other nominees included Control, Moliere, The Holiday, Feast of Love, The Savages, Shoot Em Up, and Dog Altogether.
